Worst hunting call app ever

I got this app for the elk call sounds to train my kids to use their calls. It would be helpful if the guy running the call actually knew what an elk sounds like. And to get more than one sound, you must upgrade... Horrible!
Theres way better apps out there for free. I gave this app 1 star only because 0 wasnt an option.
